Answer 1

here a basic code that reads and parses an remote xml file:
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
public class SAXParserExample extends DefaultHandler {
     StringBuffer buffer;
     String urlString = "http://nds.nokia.com/uaprof/NN95_8GB-1r100.xml";
     public SAXParserExample() {
     public void runExample() {
          parseDocument();
     private void parseDocument() {
          // get a factory
          SAXParserFactory spf = SAXParserFactory.newInstance();
          try {
               // get a new instance of parser
               SAXParser sp = spf.newSAXParser();
               URL url = new URL(urlString);
               HttpURLConnection httpSource = (HttpURLConnection) url.openConnection();
               // parse the file and also register this class for call backs
               sp.parse(httpSource.getInputStream(), this);
          } catch (SAXException se) {
               se.printStackTrace();
          } catch (ParserConfigurationException pce) {
               pce.printStackTrace();
          } catch (IOException ie) {
               ie.printStackTrace();
     // Event Handlers
     public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
          System.out.println("+++ start of element: " + qName);
          buffer = new StringBuffer();
     public void characters(char[] ch, int start, int length) throws SAXException {
          buffer.append(ch, start, length);
     public void endElement(String uri, String localName, String qName) throws SAXException {
          System.out.println(buffer.toString());
          System.out.println("+++ end of element " + qName);
     public static void main(String[] args) {
          SAXParserExample spe = new SAXParserExample();
          spe.runExample();
}you have only to change the urlString and adapt to your needs.
hope it helps
